【正文】 language. It is flexible, convenient and pact in structure. What’s more it can be applied in a large of fields and has good portability. We choose Keil C language integrated development environment which shows Windows interface that generates object codes efficiently. The majority of assembly language codes generated are very pact and easy to understand. Then the program is burnt into SCM by ISP, a STC download programming software, which is easy to operate. The main program is shown as below. Void main () { ports()。 Time()_init()。 While(1) { if(P1^0==0) ……. } } The signals of photoelectric switch are detected by query mode. With interruption subroutine, the corresponding microcontroller produces conversion of high and low voltages. The interruption subroutine is shown as below. P1^1=0。 delay(m)。 P1^1=1。 delay(m)。 P1^3= 0。 13 13 P1^4= 0。 In main program this interruption subroutine is called for several times. That generates pulses to drive the stepper motor to work. In this experiment we set fullstep and reverse mode, which can be seen in the interruption subroutine. 4 TEST RESULTS After the hardware circuit is built pletely, the program is burnt into the SCM. In order to easy the experiment, the three output ports of SCM, , , , which should be connected to L297, is connected to three light emitting diodes, as shown in Figure 6. That the light emitting diodes are light means to output high voltage. And that they are off means to output low voltage from SCM. In order to facilitate observation, the output of the relay is also connected to a lightemitting diode instead of scissors. At the beginning, the four lightemitting diodes are all light. The results of the experiment show that when some object is passing the transmitter and the receiver of the photoelectric switch, that is to say, when the photoelectric switch detects some object, the lightemitting diode of begins to flash, which shows pulses are generated. At the same time the lightemitting diodes of and are off immediately, which means the stepper motor begins to work with the forward and halfstep mode. After a period of time, the lightemitting diode connected to the output of the delay are off first and light immediately, which means that the switch opens first and then closes. That act means the scissors cut off the packing tape first and then open, waiting for the next move. 5 CONCLUSION This experiment simulates the progress of the pipeling control, using stepper motor driven by SCM. It is noteworthy that in practice the output voltage is pulled down to be low and unstable because of the loads, so voltage follower and optocouplers are introduced here for antiinterference. This article bines SCM and the stepper motor to simulate packaging lines control. This 14 can be achieved by SCM with programming instead of mimic channel or digital circuits. This controltechnology which can improve the system performance does not dependent on hardware but onsoftware. It is called the microcontrol technology. With the development of microcontrol technology, the automatical and intellectual level will be improved continuously in packaging industry.
